✨ Climate Change Data Collection Rules
964 NEW ZEALAND GAZETTE, No. 34 26 MARCH 2010
(d) any of the activities listed in Part 4 of Schedule 3 of the Act carried out as part of the
activity; and
(e) the use of electricity used as part of the activity.
-
Emissions must be calculated using the applicable formulae and emission factors specified in these
data collection rules and in the specified template. Direct measures cannot be used as a substitute. -
Emissions from the direct use of natural gas/coal as a feedstock must be calculated as zero when
either (1) the feedstock is used to produce an obligation fuel defined in the Climate Change (Liquid
Fossil Fuels) Regulations 2008, or (2) the production of the output is eligible to earn emission units
under the Climate Change (Other Removal Activities) Regulations 2009. -
Emissions for which no obligation exists under the Act due to an exemption made by Order in
Council under section 60 of the Act must be calculated as zero. -
Total emissions from a heat/steam plant must be allocated to an activity in proportion to its use of the
output of the plant. Total emissions from a co-generation plant must be split between heat/steam and
electricity emissions on the basis of relative efficiencies of production, using efficiency rates of 80%
for steam and 35% for electricity, then the heat/steam emissions must be allocated to the activity in
proportion to its use of the output of heat from the plant.
Emissions allocated to heat/steam production must be estimated using the following formula:
EH = (H / eH) / ((H / eH) + (P / ep)) * ET and Ep = ET - EH
Where:
EH = emissions allocated to steam production
H = steam output (energy)
eH = assumed efficiency of steam production
P = delivered electricity generation (energy)
ep = assumed efficiency of electricity generation
ET = total direct emissions of the CHP system
Ep = emissions allocated to electricity production
- The following specific formulae must be used in estimating direct emissions:
Coal
Emissions = (AL × CVL × EFL) + (ASB × CV SB × EF SB) + (AB × CV B × EF B)
where:
A = tonnes of coal consumed for different varieties, including L = lignite, SB = sub-bituminous, B = bituminous
CV = calorific value of the coal class used
EF = relevant emission factor for the relevant coal class.
Natural gas
Emissions = A × EF
where:
A = consumption of natural gas (in terajoules, or tonnes if LPG)
EF = emission factor for natural gas (use either one for the appropriate field(s), if known, or the
national average if the gas field(s) is not known).
